PERMUT
The PERMUT function returns the number of permutations for a given number of objects that can be selected from a total number of objects. Both arguments are number values.
PERMUT(num-objects, num-elements)
num-objects: The total number of objects. num-objects must be greater than or equal to 0.
num-elements: The number of objects to be selected from the total number of objects in each permutation. num-elements must be greater than or equal to 0.
Notes
Permutations are not the same as combinations. The order of the items in a group is ignored for combinations but not for permutations. For example, (1, 2, 3) and (3, 2, 1) are the same combination but two unique permutations. If you want the number of combinations rather than the number of permutations, use the COMBIN function.
